Designed for ECG testing as well as vital signs monitoring in surgery and
dentistry, the PM4 offers:
● ECG (with
esophageal probes)
● Core-body
Temperature
● Airway-direct Respiration
● Pulse Oximetry
Easy-to-use Digital Documentation Capability
The PM4 automatically saves monitoring records and ECG tracings on a USB
flash drive (see below). Simply plug the flash drive to the USB port on the
monitor, and then take the flash drive to your computer to transfer saved
information to the computer. You can review the information, print with any office laser or ink-jet printers (on 8.5"X11" plain papers), and integrate the data to the patient's
file using your existing veterinary practice management software (compatible with all
practice management software on the market).

Simply insert an
esophageal probe into the esophagus of the patient, place a SpO2 sensor on the
tongue, and connect an airway sensor between the endotracheal tube and the
breathing circuit. There are no leads and sensors on the patient's body.
Imagine the convenience.

Available in four different sizes, suitable for animals from lizards to large dogs, VetSpecs® esophageal probes are developed specifically for registering ECG, heart rate, and core-body temperature in anesthetized patients. It takes only seconds to insert the esophageal probe. Once placed, the probe will stay in position the whole time and register large and interference-free ECG even in the smallest cats and dogs. There are no leads and sensors on the patient body, making monitoring in veterinary patients easier than ever before.
The PM4 comes standard with a set of three
esophageal probes for cats and dogs of all sizes.
VetSpecs® airway-direct respiration technology employs an airway sensor (see
below) inserted between the endotracheal tube and the breathing circuit.
This cost-effective technology provides real-time respiratory waveforms, a respiratory
rate, and a digital respiratory sound with apnea alarm, and works
effectively in all intubated veterinary patients
regardless of respiratory volume and rate.

Unlike most pulse oximeters or monitors on the market, the
PM4 offers the next-generation digital pulse oximetry, with a wide dynamic
range to work effectively on legs and toes
as well as on the tongue. The PM4 comes standard with two SpO2 sensors, a lingual sensor
and a leg/toe sensor (see below). The leg/toe sensor can work on the
Achilles tendons, distal legs, paws, and toes, especially useful for
monitoring in dentistry.

For ECG testing, simply attach three leads (see below) to the patient. The
PM4 will automatically enter into ECG mode, displaying cascaded three lines
of ECG on one screen, and continuously save ECG on the flash drive for up to
one hour. The monitor automatically starts saving ECG upon registering valid
ECG, and stops recording when ECG is no longer registered.
